About coding head abrasion
The ICD-10-CM code for head abrasion is S00.91 (Abrasion of unspecified part of head). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S00.91.
Within S00.9, choose S00.91 (Abrasion of unspecified part of head) only when documentation doesn't support a more specific option: unspecified superficial injury of unspecified part of head (S00.90), Blister (nonthermal) of unspecified part of head (S00.92), contusion of unspecified part of head (S00.93), external constriction of unspecified part of head (S00.94), superficial foreign body of unspecified part of head (S00.95), insect bite (nonvenomous) of unspecified part of head (S00.96) and other superficial bite of unspecified part of head (S00.97).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
